Ignition oven NCAT

This ignition oven is an analyzer that determines the asphalt content in a sample by igniting the sample.

The asphalt sample is bathed in oxygenated air and weighed continuously during the ignition process.

The software identifies the end point of the ignition and indicates the end of the test. A printer outputs the results.

The hot asphalt mix sample is weighed, divided into equal parts and placed in two reinforced baskets mounted on a tray assembly. The complete assembly is placed on the tray on the oven fl oor. The tray is mounted on four ceramic supporting tubes that, in turn, are placed on the platform of a digital scale. A fan pushes ambient air through the holes in the four ceramic support tubes located at the base of the chamber. This oxygenated air saturates the asphalt sample laid out to facilitate its ignition and incineration.

The volatile elements that are released are later oxidised when they pass through a ceramic fi lter heated to 750ºC in a chamber over the main chamber.

After between 20 and 40 minutes, depending on the weight of the sample, the oven detects the end of the test when all the bitumen has been incinerated and stops emitting a whistle. A report is printed showing the percentage of bitumen per aggregate and mixture.

It is supplied with two sample basket assemblies, printer, four rolls of printer paper, heat-resistant gloves, head gear with face shield, aluminium cool down plate, cool down safety cage and basket brush.
